Aside from hypertension and the results of hypertension, what health risks does a high sodium diet have.

This is interesting, but it doesn’t show how serious the risks are for those diseases, if there is a 10% higher risk or a 500x higher risk.
Asthis study demonstrates, blanket and non-specific advice to reduce dietary salt intake may be vastly overvalued and overemphasized.
Aren’t those risks enough? IANAD, but I suppose that an electrolyte imbalance is a possibility.
I should be more complete and note that the putative benefit of reducing one’s salt intake extends to beyond cardiovascular disease. Specifically, there is some evidence (but no randomized control trial of which I’m aware) that high dietary salt promotes osteoporosis in women.
Basically, the more salt you eat, the more you excrete it in the urine. As it turns out, however, urinary salt excretion (i.e. sodium excretion) is coupled to urinary calcium excretion. Hence, a high salt diet may lead to excessive urinary loss of calcium with a resultant tendency towards osteoporosis. (Here is one of many references in this regard)
